“Babies are used to sleeping with a rhythm [in utero],” says inventor Dr. Harvey Karp, co-founder and CEO of Happiest Baby, maker of the Snoo. “Why should we rip that away the instant they’re born?” The popular bassinet lulls infants with automated rocking and shushing. It also secures them on their backs, reducing the threat of sudden infant death syndrome—which is why, in March, the FDA granted De Novo approval to the Snoo, making it the first medical device to be approved for infant sleep. Happiest Baby hopes insurance coverage for the $1,700 Snoo comes next.
